Felix Rudolphi commented on PDFBOX-2976:
----------------------------------------

Oh, yes, indeed, I should have had a look at that. I will notify the owner of 
the website to fix that problem. However, after having removed the HTTP header 
from the file, it still gives me the same problem, otherwise I could have 
repaired this internally as well. The file size is now consistent with 
Content-Length in header, so I assume there are no other protocol artefacts.

Thanks very much, and sorry for the trouble.
